The above citations to literature are all believed to refer to 

 this species. The record by Viereck of this species as a parasite of 

 Calandra oryzae is undoubtedly erroneous as it is exclusively a 

 secondary parasite issuing from the cocoons of various species of 

 Apanteles and possibly other Ichneumonoidea. (See discussion 

 under Eupteromalus viridescens, ante). 



FAMILY EULOPHIDAE. 



Genus Ceratoneura Ashmead.

 ington, D. C., 1917, p. 2. 



In describing Ceralotetrastichodes which he bases upon the 

 species Ceratoneura pretiosa Gahan, Girault states that this "may 

 not be a genus at all." The writer is of the opinion that this 

 statement is fully warranted. Girault bases the genus entirely 

 upon antennal characters. As shown by the following notes the 

 antenna of C. pretiosa does not differ in any essential detail from 

 that of C. peliolata Ashmead, genotype of Ceratoneura. Neither 

 do the two species differ otherwise in any characters worthy of 

 generic rank and Girault's genus must therefore be considered a 

 synonym.
